Daphnia magna or Moina?

Does anyone here cultures their own daphnia? I intend to start 3 sequential batches of daphnia, and make live food available to my tank almost daily.

Which daphnia do you all think is more appropriate for the fish I have? Magna or moina?

Currently I have:
Cardinal Tetra (Paracheirodon axelrodi)
Long-finned Halfbeak (Hemirhamphodon pogonognathus)
Betta Splendens
Tetraodon biocellatus

I am already collecting live snails to my dwarf puffers from LFS, for free of course. People are getting rid of their snails, but I am not having enough.

Daphnia is intended to supplement cardinal and halfbeak's diet. Currently these 2 species rely solely on flake and freeze dried blackworms.

Either one would work. Moina is half the size of magna, but your fish are capable of eating both.

Thanks!

What would you recommend of feeding daphnia? I don't think I can make green unicellular algae to grow as fast as I'd like. Is there any simple recipe that you use to keep daphnia's nutritional value high with HUFA?

Greenwater! Seriously, it works wonders for these guys and one of the reason that I put my tank out of whack. Not really hard to get it going either.

Also, have you considered microworms as another source of live food?

Wouldn't micro worms be too small as food? What would happen to uneaten micro worms?

The reason I selected daphnia is mainly because I could gut feed nutrients to them much the same way as artemia, without the saltwater hassle of artemia. The other reason is if left uneaten, daphnia will not die off in typical planted tanks, and will offer fish the chance to hunt them down when they are hungry.

I've also thought about tubifex worm culture also because they will continue to live in the tank (substrate) to help clean up detritus, and provide a good hunting opportunities for fish.

How do you culture micro worms?
